Gotham City Impostors beta announced via moving pictures

Wow, finally a Gotham City Impostors video that shows actual gameplay (yes, I know they already exist, but I don't think I've seen one yet - until now). According to gamesradar.com, the beta will run from December 15 to 20. They also have a link to the page at Eurogamer where fans can go to get beta keys while they last. The beta is available to both PS3 players and Xbox 360 players.
